Now that I have my '80 back (refinished bbl + trigger), I did the, "tap test." It certainly sounds different from my '79, but that's all I can say. Since they're of different dimensions and amount of metal used (more in the long rail's frame up front) I can't confirm any, "super hard metal theory," 100%. I will however say that
both are solidly built and accurate every time I've taken them out!
